Article of the tent or shelter type
The present invention relates to an article ( 1 ) of the tent or shelter type including a roof element ( 2 ) at least partially covering a shelter area ( 3 ), said roof element including a main flexible panel ( 4 ) having opposite outer ( 4 a ) and inner ( 4 b ) faces, the inner face ( 4 b ) being intended during operation to be oriented across from said shelter area ( 3 ). Characteristically, the inner face ( 4 b ) has an emissivity rate (%) of far infrared rays lower than the emissivity rate (%) of far infrared rays of the outer face ( 4 a ).
1. An article comprising a roof element at least partially covering a shelter area, said roof element including a flexible main panel having opposite outer and inner faces, the inner face being intended during operation to be oriented across from said shelter area, the outer face being intended during operation to be oriented across from the sun's rays, wherein said inner face has an emissivity rate (%) of far infrared rays lower than the emissivity rate (%) of far infrared rays of said outer face, and wherein said outer face is arranged so as to reflect the solar rays, and wherein the article is one of a tent or a shelter.
2. The article according to claim 1 , wherein said emissivity rate (%) of the far infrared rays of the inner face is less than at least 10% points at the emissivity rate (%) of the far infrared rays of said outer face.
3. The article according to claim 2 , wherein said emissivity rate (%) of the far infrared rays of the inner face is less than at least 20% points, at the emissivity rate (%) of the far infrared rays of said outer face.
4. The article according to claim 1 , wherein said shelter area includes an inner room at least partially covered by said roof element, said roof element and the inner room being arranged so as to be spaced apart at least locally by a layer of air having a width d.
5. The article according to claim 4 , wherein d is greater than or equal to 7 mm.
6. The article according to claim 1 , wherein said outer face of the main flexible panel has a reflection rate greater than or equal to 40%, measured according to standard NF EN 410 April 2011.
7. The article according to claim 1 , wherein said outer face of the main flexible panel is at least partially coated with a first reflective component, and said inner face is at least partially coated with a second component, said first and second components being selected such that said first component has an emissivity of far infrared rays (%) greater than the emissivity of the far infrared rays (%) of said second component.
8. The article according to claim 7 , wherein said first component and said second component are metal particles.
9. The article according to claim 7 , wherein said first component is titanium dioxide and said second component is a powder of aluminum or silver.
10. The article according to claim 7 , wherein said outer face is at least partially coated with a first film of a first polymer and said first component.
11. The article according to claim 10 , wherein said first film is colored.
12. The article according to claim 10 , wherein said inner face is at least partially coated with a second film in at least one polymer capable of making said inner face impermeable to water.
13. The article according to claim 12 , wherein said second film includes said second component.
14. The article according to 12 , wherein proportion by weight of the second component in the second film is less than or equal to 75%.
15. The article according to 14 , wherein said proportion by weight of the second component in the second film is less than or equal to 50%.
16. The article according to claim 10 , wherein said polymer is chosen alone or in combination from among the following polymers: polytetrafluoroethylene, polyurethane, polyethylene terephthalate, ethyl vinyl acetate (EVA).
17. The article according to claim 10 , wherein proportion by weight of the first component in said first film is less than or equal to 75%.
18. The article according to claim 17 , wherein said proportion by weight of the first component in said first film is less than or equal to 50%.
19. The article according to claim 1 , wherein said inner face is completely or partially coated with a metallized film.
20. The article according to claim 1 , wherein said inner face is completely or partially coated with an aluminized film.
21. The article according to claim 1 , wherein said main flexible panel is a textile panel.
22. The article according to claim 1 , wherein the shelter is one of a parasol, an umbrella, a canopy, or a blind.
